Caramel Filling ?

on a food TV challenge i saw a cake that was used, had one layer white cake,one layer chocolate and filled with caramel filling. the judges loved it. i have a birthday cake coming up. i want to try something new,like this. any ideas?

I had left over caramel and ganche that I wanted to use so I made a cake and mixed the 2 together. My daughter and her friends said it was the best filling they ever had. It was 1/2 and 1/2. I was afraid that the caramel by itself would be too thin because I had read several people mentioning that they have had problems with caramel leaking. I think the ganache helped thicken and stabilize it.

consider a dulce de leche filling. it's very thick and won't seep into the cake. you will, however need a dam so it doesn't ooze out.

1. buy a can of sweetened condensed milk. DON'T OPEN IT.2. put it in a saucepan an COVER it with water.3. once it comes to a simmer, turn it to low, cover the pan and SLOWLY simmer for 3 to 4 hours. 4. turn off the heat and just let it cool for a few hours.
